There are a lot of problems in South America now. The biggest environment crisis is pollution. The land pollution, water pollution, and air pollution. Acroding to the reports, although 81 percent of solid waste generated by towns and cities in the region is collected, only 23 percent receives adequate treatment. Not much better than in the case of sewage, only 14 percent of which is treated. In addition, soil degradation affects 15 percent of Latin America - 26 percent of Mesoamerica and 14 percent of South America. So the land will lose for agriculture, and become the food shortage. Soil erosion - the cancer of our land - deforestation and water and air pollution, and there are no figures indicating that they have improved, with the exception of a reduction of ozone-thinning pollutants.
